NEAR BEAVERTON, Ore. (KOIN 6) — Investigators are trying to determine what caused a Washington County home and five cars to catch fire.

Emergency dispatchers confirm the fire in the 900 block of Northwest Joy Avenue was reported around 1 a.m. Saturday.

A spokesperson with Tualatin Valley Fire & Rescue posted to its Twitter account that the fire had been extinguished around 1:30 a.m., and that at least two cars were damaged by fire.

Other TVF&R Twitter posts confirmed that all of the residents were able to evacuate the home.

The person who called 911 told dispatchers that the residents had just arrived home to find the fire, and were attempting to use a fire extinguisher and garden hose to put out the fire.
One man suffered burn injuries to his hands and arms, and was transported to a local hospital with non-life threatening injuries. Two adults and two children were displaced by the fire, officials said.

When firefighters from North Beaverton Station 61 arrived, they found heavy flames coming from the home including two vehicles that were parked outside.

The Washington County Sheriff’s Office posted to its official Twitter page that Northwest Joy Avenue had been closed between Northwest Cornell Avenue and Northwest Dale. The streets have since re-opened.

“TVF&R reminds everyone that fire extinguishers may be an effective tool for a small fire but if the fire continues to burn after using a fire extinguisher, exit to safety immediately and call 9-1-1 from a neighboring home,” a spokesperson said in an prepared statement.
